Protein or the physical region of the protein that participates in chemical catalysis. In solution proteins also undergo variation in structure through thermal vibration and the collision with other molecules. Proteins can be informally divided into three main classes, which correlate with typical tertiary structures: globular proteins, fibrous proteins, and membrane proteins. Almost all globular proteins are soluble and many are enzymes. Fibrous proteins are often structural, such as collagen, the major component of connective tissue, or keratin, the protein component of hair and nails. Membrane proteins often serve as receptors or provide channels for polar or charged molecules to pass
Revival Soy milk protein shakes. Research also has suggested that Revival Soy protein shakes might support healthy skin, hair, and nails. A research study conducted by a board-certified dermatologist assigned postmenopausal women (50–65 years of age) with mild to moderate photoaging to drink either one Revival Soy protein shake or to remain on their normal diet for 6 months. After 6 months of dietary soy consumption, improvements were seen in facial wrinkling, discoloration, and overall appearance. Also, improvement was noted in nail roughness, ridging, flaking, splitting, and overall appearance at the end of the intervention period. Improvements in hair health were evident
