“Ascorbic acid is needed for a variety of biosynthetic pathways, by accelerating hydroxylation and amidation reactions. In the synthesis of collagen, ascorbic acid is required as a cofactor for prolyl hydroxylase and lysyl hydroxylase. These two enzymes are responsible for the hydroxylation of the proline and lysine amino acids in collagen. Hydroxyproline and hydroxylysine are important for stabilizing collagen by cross-linking the propeptides in collagen. Defective collagen fibrillogenesis impairs wound healing. Collagen is also an important part of bone, so bone formation is also affected. Defective connective tissue also leads to fragile capillaries, resulting in abnormal bleeding.” – wikipedia.com on scurvy
A gallery of images from Austin-based artist Sarah Stevens‘ current exhibit at the City of Austin’s Dougherty Arts Center. The Julia C. Butridge Gallery is one long space, and Stevens has loosely divided her show into two parts, one side mostly consisting of drawings and wall-mounted constructions, while the other is largely filled with freestanding constructions/conglomerations of mixed media (all kinds of textiles from yarn to cut-up upholstery, plastic beads, duct tape, ink-on-vellum “lichen” and more,) with the entryway providing a neutral buffer between. She achieves an unforced balance, and the sculptures on the east side of the gallery particularly benefit from their grouping together. The work on view shows the increasing coherence in Stevens’ last few years of intuitive exploration of reproduction, sexuality (and asexuality,) domesticity, and their entanglements with our culture of consumption – an instantly recognizable body of work, with boundaries between her earlier delicately compulsive ink drawings and garishly colored, sprawlingly anatomical and slightly grotesque sculptures increasingly being blurred and in some cases now erased.
