Accessory pigments include chlorophyll b (also c, d, and e in algae and protistans), xanthophylls, and carotenoids (such as beta-carotene). Integumentary Structure/Function The Structure of Sebaceous Glands and Their Relationship to Hair Follicles Figure 5-6 But over the past 30 years, it has become apparent that they have a second function, no less important than the first. •The current systems of classification of algae are based on the following main criteria: o kinds of photosynthetic pigments, o type or chemical nature of photosynthetic energy storage products o photosynthetic membranes’ (thylakoids) organization and other features of the chloroplasts. Vitamin A is important for normal vision, gene expression, reproduction, embryonic development, growth, and immune function. Carotene persists in leaves even when chlorophyll has disappeared. ... Carotene, found in plants such as carrots, can accumulate in the stratum corneum, and hypodermis can give the skin an orange hue. Carotene is a much more stable compound than chlorophyll. The experiment was carried out and it was proven that: Beet leaves contain: Carotene, Xanthophylls, Chlorophyll A and B, and Anthocyanin as a pigment in the leaf. C-Phycocyanin (blue pigment protein), in particular, has been reported as a potent peroxy radical scavenger, platelet aggregation inhibitor, and proliferation inhibitor of cancer cells in vitro and in vivo . Table 1:Pigment composition of … Also, oxygenated hemoglobin can give the skin a pink hue in lighter-skinned inviduals. Integumentary Structure/Function The Structure of Sebaceous Glands and Their Relationship to Hair Follicles Figure 5-6 Vitamin A is a group of unsaturated nutritional organic compounds that includes retinol, retinal, retinoic acid and several provitamin A carotenoids (most notably beta-carotene). Accessory photosynthetic pigments, including chlorophyll b and beta-carotene, absorb energy that chlorophyll a does not absorb. Chlorophyll is a green pigment found in the leaves and stems of plants that plays a significant role in photosynthesis. Thus, current dietary patterns appear to provide sufficient vitamin A to prevent deficiency symptoms such as night blindness. Describe the accessory structures of the skin and the functions of each; ... a cell that produces the pigment melanin. Beta-carotene, alpha-carotene, and beta-cryptoxanthin have provitamin A activity (see Vitamin A; von Linting, 2012). Melanin gives skin its tan or brown coloration and provides the color of brown or black hair. C) maintenance of body temperature.
