A myocyte (also known as a muscle cell) is the type of cell found in muscle tissue.Myocytes are long, tubular cells that develop from myoblasts to form muscles in a process known as myogenesis.ardiomyocytes are the muscle fibres that form the chambers of the heart, and have a single central nucleus. Skeletal muscle fibers help support and move the body and tend to have peripheral nuclei. Smooth muscle cells control involuntary movements such as the peristalsis contractions in the oesophagus and stomach.
Before I tell you about the many benefits of carotenoids, it is helpful to know what they are and where they come from. Carotenoids are the phytochemicals that make plants colorful and are responsible for the burst of color in fall foliage. They shield plants from sun-induced free radical damage. Considering plants spend their entire lives in the sun, these carotenoids, along with other antioxidants, provide powerful protection. Brightly colored fruits and vegetables such as squash, sweet potatoes, leafy greens, and tomatoes contain carotenoids. And just as carotenoids protect plants, they protect you. The most abundant carotenoids in human tissues are alpha-carotene, beta-carotene, beta-cryptoxanthin, lutein, zeaxanthin, and lycopene. The first three can be converted in the body to vitamin A, and the entire carotenoid family provides multiple benefits for overall health.
The richest sources of beta-carotene are yellow, orange, and green leafy fruits and vegetables (such as carrots, spinach, lettuce, tomatoes, sweet potatoes, broccoli, cantaloupe, and winter squash). In general, the more intense the color of the fruit or vegetable, the more beta-carotene it has.eta-carotene is a pigment found in plants that gives them their color. The name beta-carotene is derived from the Latin name for carrot. It gives yellow and orange fruits and vegetables their rich hues. Beta-carotene is also used to color foods such as margarine.
