What Specific Protein Molecules Are Involved In Muscle Growth/repair

What is the best protein to build lean muscle?

It would help if you could have elaborated on the following:1. Which country do you live in?2. What is your goal (Gaining mass or losing weight?)Taking both these hypothesis,I am a huge fan of Acacia Whey Totale and Acacia Soy Totale.1. Soy Totale:I think it is the best for gaining lean muscles if you are not a fitness freak.Have a look at their nutritional value.As you can see from the image that i pulled from their website, total calories in Soy totale are around 120. Which is awesome. What is amazing is that the calories from Fat is 15 and from Carbs is around 8 (2 g carbs). This is outstanding! There is 0 trans fat and 0 Cholesterol.2. Whey Totale:If you work out then there is nothing better than Whey Totale. Take a look at their nutritional value:26 Grams of protein (> 80%). Totale calories - 111, Carbs .65 Grams (2.6 calories), Calories from fat - 6.8 (.74 grams).This is not a coincidence, Both these products are made using Acacia Lean Muscle formula as described on their website.If you are looking to gain mass (or weight), you may want to consider:Acacia Gladiz™ Mass Gainer 6.6 lb Chocolate This is made using the same Lean Muscle formulae and if you hit the link you would know about the nutritional value. You may compare this with other brandsConsidering that you have tried almost all the other brands i will not waste your time telling you about them. This is a newer brand and has created waves atleast in India due to their Lean Muscle Formula. If you live in India you may order it from their website, (acacia world) Buy the best Whey Protein, Mass Gainer, Fat Burners and other Health Supplements online in IndiaRest you may also want to compare other products, on (Health Kart)Online Shopping for Health Care Products, Protein, Vitamins & More at HealthKart.com or (Muscle Guru)Whey Protein, Mass Gain, Muscle Gain, Fat Loss, Bodybuilding & Fitness Supplements in India

What contributes to muscle growth?

Various factors stimulates the muscle growth.The main and important mechanism or the engine is mTOR pathway(mammalian target of rapomysin).ill try to make it as simple as possible...:DAs we know proteins are the building blocks,presence of protein is sensed by the mtor a protein,in-turn activates few enzymes like  p70S6k,4e-bp1,elF4G causing increased protein  synthesis leading to the muscle growth and proper repair.Factors triggering mTOR activity are1.exerise-activates protein synthesis via phosphorylating certain portions of a protein named p70S6 kinase (p70S6k) in a pathway that is also apparently independent of mTOR2.BCAA-especially leucine is very important.3.Insulin toooo...high carb diet ofently after workout may work well.this doent mean that adding bcaa to diet alone will increase the bulk,proper calorie intake and protein intake is very important.The bulk of post workout protein synthesis occurs from roughly 4-24 hours after the workout. BCAAs have their ‘doubling’ effect in the 1-3 hours window post exercise.{leucine rich food are poultry-chicken breast,pumpkin seeds,soya beans,fish.....}

Describe how nitrogen becomes part of a protien molecule in a muscle of a herbivore?

when a herbivore eats plant protein , it is digested in stomach by pepsin protease into poly peptides then it is digested in the duodenum by pancreatic juice containing pancreatic protease which digests poly peptides into smaller peptides then is digested in the ileum into non-essential amino acids by trypsin protease . then these amino acids are absorbed into the blood stream by the villi in the small intestine . then these amino acids are transported to the liver through the hepatic portal vein . then in the liver excess amino acids are changed into ammonia by removing the amine group and then ammonia is transformed into urea that is transported by blood to the kidney to be excreted. then the amino acids in the liver which are not excess to body requirements are transported through blood to all body cells to be used in repairing cells and building new protoplasm especially in the muscles . In muscle cells the non-essential acids undergo a process in which the molecules and atoms (carbon, hydrogen, oxygen and nitrogen and sometimes sulpher or potassium )are rearranged to form new kinds of amino acids like animal essential amino acids that form the proteins in a herbivore muscles. I hope I made this issue clear to you.

How much protein should be eaten a day to maximize muscle building?

Building and repairing muscleHow much protein is needed for maximum muscular growth? Beginning bodybuilders are often confused as to how much crude protein they should be consuming on a daily basis. The average amount recommended in bodybuilding and advanced fitness books is 80 grams per day. This has been accepted as “staple truth” for many decades, until sport scientists began looking at how our bodies utilized protein when the muscles are under stress. Current studies suggest that if you’ve been consuming just 80 grams or less of crude protein per day, you may have been eating too little to encourage maximum muscle growth. It appears that in order to truly maximize the growth potential of all your major muscle groups, you need to consume at least 1 gram of protein for every pound of your current body weight. For more information check out my FREE ebook you can download here [1]I have seen many bodybuilders who gradually increase their protein intake as they slide up the intensity of their workouts (sometimes 50%-70% their initial protein intake) and they get wonderful results. Why do we need so much protein in your diet? Protein is one of the most essential building blocks needed by the human body for normal function. Our bodies literally cannot grow without protein. That’s why people who are not able to consume protein regularly often suffer from protein malnutrition and they look bloated because their body cells do not have sufficient protein for normal production of cellular walls, which keep water inside the cells.Bodybuilders are a special class of fitness buffs because they engage in demanding activities that put intense strain on the muscle fibers. Muscle fibers are built with protein; that’s how it has always been in the Animal Kingdom. Logically speaking, if you want your muscles to grow in size while you are applying regular stress and strain, you need to feed them more with the right type of nutrient. Our bodies utilize all 3 macro-nutrients for energy but only protein satisfies the requirement for physically rebuilding and repairing muscle fibersFor more information check out my free e book you can down load right here

Is protein necessary for body building?

Why is protein necessary?Protein is an important component of every cell in the body.….... Your body uses protein to build and repair tissues. You also use protein to make enzymes, hormones, and other body chemicals. Protein is an importantbuilding block of bones, muscles, cartilage, skin, and blood.Why it is necessary for body building?Delivering your body a constant supply of Protein throughout the entire day is essential for optimum muscle growth. Protein is made up of amino acids. Amino acids are the building blocks of your muscles and body. Without them, it would be impossible to build, repair or even maintain muscle tissue.

When putting on muscle mass, what matters most: calories or protein?

I'll take a stab at this -- since there seems to be a mixed bag of answers.

Basically - you need both.

First, if your wanting to build up mass, you need lots of energy to do this. Calories are energy. Energy to move, energy to lift, and energy to build.

During the bulking phase, you need lots of excess energy to make all your workouts progressive. Don't worry about excess fat. Not yet at least. This comes later. It's much harder to put on muscle. It's even harder to do without enough energy. In contrast, it's easier to reduce body fat when you have more muscle.

Muscle movement energy comes from fats and carbs. The energy (calories) in protein is reserved to enable the amino acids to work, building up cells and body tissue. (muscle fiber, hair, fingernails, etc.) anything that grows, get's its energy from "the calorie" within the protein molecule.

The energy in proteins is actually a medium chain trigyceride (MCT). If the body needs more "movement" energy, it could steal this chain from the protein. You want to avoid this. The protein itself doesnt convert to fat (thus energy), just the MCT does. Without the MCT, the amino acid becomes useless, and gets expelled. Most calories from protein rich foods can be measured from the "calories from fat" notation.

Like others said - proteins are building blocks. Fair enough.

They are just a pile of bricks. The building materials. But a pile of bricks is pretty useless unless you have something to actually do the building and assemble these bricks into something useful - like muscle or body tissue. The "builder" is your "growth hormones". Unless the body calls for growth hormone -- all the bricks in the world won't do anything. The builder (hormone) get's it's instructions from genetics, aka "your Blueprint". This tells the hormone to build or repair, based on genetic instructions, using proteins as the building material.

And that's basically how it all works in a nutshell.

So, excessive proteins without intensive training or real work are fairly useless. It's just healthy calories because the calories from fat will store as body fat -- but the protein nutrient itself will be expelled if not needed.

If your primary source of proteins are shakes -- keep this in mind. Shakes are "supplements". Meaning, "in addition" to real food. Not instead of.

What does protein do for your body?

Protein gives you energy, growth, helps grow/ repair cells, produces neurotransmtitters that keeps the brain moving smoothly and gives other nutrients. Some protein foods are Milk, dairy foods, meat, fish, chicken, red meat, eggs, beans, lentils, nuts, tofu and soya.

So remember, eat protein!!!!!

What does protein do for the body?

Rebuilds cells, repairs tissue particularly muscle.
